This paper presents the design of an 800 V 11 kVA three-level three-phase active neutral point clampedinverter, utilizing 650 V gallium nitride enhancement-modehigh-electron-mobility transistors, to evaluate its feasibility in electric traction systems. The modular approach of thepresented power converter design is detailed discussed and the different printed circuit boards composing the power converter are presented, together with critical design issues. The paper includes the gate driver design, as well as the thermal analysis and parasitics extraction using ANSYS Q3D Extractor.
